Detailed Description

The session is what performs the actual speech recognition. It has methods to input audio, and it calls your given handler with decoded results.

You need to pass a Model when constructing a Session.

Constructor & Destructor Documentation

◆ AprilSession()

AprilAsr.AprilSession.AprilSession	(	AprilModel	model,
		SessionCallback	callback,
		bool	async = `false`,
		bool	noRT = `false`,
		string	speakerName = `""`
	)

Construct a session with the given session, callback and options.

Parameters

model	The model to use for the session.
callback	The callback to call with decoded results.
async	Whether or not to run the session asynchronously (perform calculations in background thread)
noRT	Whether or not to run the session non-realtime if async is true. Has no effect if async is false.
speakerName	Unique name if there is one specific speaker. This is not yet implemented and has no effect.

Member Function Documentation

◆ FeedPCM16()

void AprilAsr.AprilSession.FeedPCM16	(	short[]	samples,
		int	num_samples
	)

Feed the given pcm16 samples in bytes to the session. If the session is asynchronous, this will return immediately and queue the data for the background thread to process. If the session is not asynchronous, this will block your thread and potentially call the handler before returning.

◆ Flush()

void AprilAsr.AprilSession.Flush ( )

Flush any remaining samples and force the session to produce a final result.

◆ GetRTSpeedup()

float AprilAsr.AprilSession.GetRTSpeedup ( )

If the session is asynchronous and realtime, this will return a positive float. A value below 1.0 means the session is keeping up, and a value greater than 1.0 means the input audio is being sped up by that factor in order to keep up. When the value is greater 1.0, the accuracy is likely to be affected.
